We've just bought an old house in Wellington. Rubbish to nonexistent insulation, no heating.

But - we may have to move in three and a half years so we don't want to spend heaps on it. We've already had to fix some of the previous owner's shoddy renovations, and we haven't insulated it yet. Yes, previously a rental with noncompliant insulation :P

Kogan do suspiciously cheap heat pumps - $1200 including shipping for an 8kW unit, $530 for a 2.7kW. Has anyone got experience with them? And who in Wellington would install a random heat pump you've bought off the internet?

Figure $1k for a back to back installation. Add at least ceiling insulation or you're wasting your money heating the planet. I'd buy locally.

Oddly I couldn't find anything about kogan heat pumps online. Be aware that some ultra cheap stuff may have a fixed speed (not inverter) compressor that needs to cycle to maintain the set point.

If you are looking to save a lot of money, you could go for a used heat pump. They sell very cheap.

But of course you need to consider that you are going to spend $700+ having it installed and if it is good value to install an cheap older unit that may need to be replaced in a few years. (and likely will be less efficient that new R32 stuff)

Of course a new one of the latter heat pump would be looking at just shy of $4k installed, so could rince and repeat a couple of times and still be winning.

Another thing is that if you're installing in Wellington a generic older unit may perform poorly at low temps compared to a modern one, or one specifically designed to handle low temps.

Speaking of which, we'll be getting rid of a works-perfectly Mitsubishi heat pump in the next couple of weeks (in Orkland) if someone wants one for a token amount, save listing it on TM.

We have three Kogan heat pumps being installed next week.

I asked and a few days later Kogan recommended an installer in Auckland who we're using at $800 x 3.

A few days after buying a sale started with 10% off - asked and Kogan gave us 10% back as store credit.

Indoor units arrived quickly via courier. Outdoor units shipped slower via Mainfreight.

Fingers crossed. Seem great value for new smart heat pumps with five year warranty!

Nope, these are inverter models, but I do see the smallest model is currently showing as out of stock. Quite a jump in size to the other two, but depending on the space you’re heating...

Edit - noting you’re in Wgtn, depending on how close to the sea you are one thing to be mindful of is rusting of the outdoor unit, and whether cheaper units will be more susceptible to this. But I can see why they’re tempting - even IOTed.

I would be careful of heatpump that a COP rating of less than 4 or similar SEER ratings.

Best units can deliver upto 6 or 7.

Thanks

Ugh, my motto is to buy once and buy right. Don't buy cheap and make it the next owner's problem.

Be careful of old heat pumps. You won’t know if it works until you’ve had it installed. You need to be confident its been removed properly and the refrigerant is in the outdoor unit.

COP of 6 or 7 is dreaming! Most don’t get above 4. Anything near 4.5 is really good.

Also if you are planning on renting it out after you leave (or sell it as a rental) it will need to be health homes compliant

Whilst I can understand not wanting to spend more than required, if this turns out to be shorter life than normal for whatever reason, it's going into landfill, whomever buys it next may need to spend on it, or you may not move and have to live with it.

What are your chances of trouble free after sales service?

I'd skip it and move to a brand sold and supported locally, even if that was simply because it will be longer before it ends up in landfill.

I agree and wouldn't buy one myself - but what if the Kogan heat pumps are okay? They're so cheap it makes me want to smell a rat.

The specs and features (R32, COP, wifi with google home integration) look good, 5 year warranty is pretty standard, when "brand name" products these days start failing, then the manufacturers start pricing parts so high (or simply make them unavailable) to "encourage you" to throw them out and buy a new one anyway. Not that I'd expect support for the Kogan product to be better - but it's probably not going to be a hell of a lot worse.

So long as they're still working properly and installed appropriately, I'd be very confident that those units would easily pass healthy homes regs.
